You are grinding too deep.
40° is the correct head angle for that grinder.
That looks pretty pokey,look at the laser mark on the side of the chain for reference ,my usg makes them like this .Okay angles are 40 on head tilt, -30 vise, -15 on the slide. Cutters seem like they have way to much hook. This is also with the stihl 7010 wheel and also 3/16 cyclone. There isn't a difference when I change wheels.
